To @ZZ whom, it may concern:

Be it known that I, JUDsoN W.IWARNER, of Oneida, in the county ofMadison and State of New York, have invented certain new and usefulImprovements in Adjustable Rapid Oouplin gs for Boiler-Drums; and Idohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form part. of thisspecification.

Thisinvention relates to means for connecting drums to boilers, andespecially` tov connections between drums and sectional boilers used forsteam or hot-water-heating. j

My invention provides adj ustablev cou plin gs which can bemovedvsidewise or up and down, so as to Lmake perfectly tight jointsbetween the boiler and drums, and which can beeasily andrapidlyconnected by an ordinary workman. not even skilled in themechanical art ofV Y quently experienced bythe most expert steamf.

iitters in connecting drums to sectional boilers, as the ordinaryconnection is made by a pipe joint threaded at both ends, whichrespectivelyscrew into threaded openings in the d rum and boilersection, and the utmost care and skill is necessary to make the jointsat both ends tight, involving large expense and great trouble. In thepresent mode, all the threaded pipe joints have to be first screwed intoythe drum, before it is placed in position,

and then screwed into the boiler side, and made fast in such position..Then the connections with the radiators are made; but should animperfect pipe or lthread cause a leaky joint, it is ncessary to removeor loosen all the other pipes in order to replace the damaged joint. BAymy adjustable rapid coup-l lings any one joint can be removed andrepacked without disturbing others in anymanner. They are inexpensive,and perfectly re-l liable.

The invention comprises a novel construction of the drums, and of thecouplings which are used to connect the drum with the water spaces ofthe boiler sections, and it consists in the combination of, andconstruction of, parts set forth in the claims, and described in detailas follows:

' Referring to the drawings, Figure l represents a detail transversesectional view through a sectional boiler and the top and bottom drums,and the adjustable connections therebetween. Fig. 2 is a detailperspective view of the top drum, showing one of the top drumsectionsemployed to lengthen the drum; Fig. 3, a' perspective view ofone of the top drum and boiler couplings. Fig. et is a'detailperspective viewof the bottom drum detached, 'showing one of the bottomdrum sections employed to lengthen the drum. Fig. 5 is a detached Viewofeone of the couplings between Abottom drum and boiler.

bottom drum, and E one-of the adjustable` couplings between such drumand boiler.

Drum B is preferably made of cast metal,

iis tubular, and as long as the ordinary sectional ,boiler to which itis connected, say six sections. It is closed at one end, and at its'other end has aflange B which is slotted or perforated for the passageof bolts B2 which secure a head B3 thereto. It also has a series ofopenings in its top, in which the ends of the radiator pipes aresecured. At one side of this drum is a dat surface l?.4 which has topand bottom flanges-b, b', which are dressed smooth. By making theseflanges continuous as shown the side of the drum and anges can bedressed in an ordinary planing machine. In this side are a series ofopenings b2 one for each section to which the drum is to he connected,and in the upper flange b, above each opening, are formed two openvertical slots or elongated holes b3, and below each opening two similarslots b4 are made in flange b'. Thus there are several slotse aroundeach opening, arranged almost equi-distant.

The coupiings O are tubular, and so as to connect with the openings inthe drum, and

-in the tops of the sections, which openings are at right angles to eachother. The end of each coupling which connects with the drum is flanged,as at O and dressed perfectly smoothv so as to it closely against theside b4 of the drum over one of the openings b2 therein. In this iiangeare formed slots or elongated holes C2, at point-s coincident with the Yslots b5, b4, around the openings, but slots or holes C2 extendhorizontally, instead of vertically, and thus stand at about rightangles lto slots b3, b4. The couplings are secured to the drum by boltsC4 passing through the co incident slots in flanges 11,6', and C', asshown in the drawings. The other end of the coupling is flanged at c,said flange having two open slots or elongated holes c', one at eachside, and a front perforation c2, which may be an open slot if desired.This flange is dressed smooth on its face to fit closely on a similarlydressed flange A2 around the mouth of the top opening A of the boilersection, and flange A2 is slotted or perforated at A3, A4, to correspondwith the slots and perforations in flange c, and the joint is secured tothe section by means of bolts c4L passing through the correspondingslots and perforations in flanges c, A2, as shown.

Each coupling C is connected to the drum and a boiler section in thismanner, and obviously each is detachable and adjustable independently ofits fellow, and owing to the open slots or elongated holes, the drum endof the coupling can be adjusted laterally or vertically and a closejoint made, even though the bore of pipe and opening b2 do not exactlyregister; andthe other end of the coupling can be adjusted laterally onflange A2 as accurate register of the bore of the joint and opening A ofthe section is not essential. Therefore if the openings in the boilerand drum are not in line, one being in advance, behind, above, below orto one side of its proper position in relation to the other, as mayfrequently occur by reason of defective, or irregular, setting of thesections, yet my adjustable connections compensate for all suchirregularities and not requiring any special adjustment can be put inplace by unskilled workmen and tightjoints made. In practice a suitablepacking may be interposed between the meeting faces of the flanges.

Drum B maybe connected at each side to the sections, in which case bothsides of the drum would be constructed as above described, but oneconnection with each section is usually sufficient.

In order to uphold and level the off side of the drinn, while making theconnections, I employ short rods F, at each end of the drum, the lowerends of which are bent at right angles, and secured to ears A5 on top ofthe front and rear sections, by a nut F. The upper ends of the rods arescrew threaded, and pass through lateral eyes B6 on the drum, and nutsf,f, are screwed on the rods respectively above and below said eyes, andby adjusting said nuts the drum can be leveled and locked rigidly inposition.

The bottom drum D has a series of openings D' in its top side with whichthe return pipes from the radiators are connected, and on the sideadjoining the sections it has a horizontally extending flange d, throughwhich are a series of openings d' communicating with the interior of thedrum by curved pipo elbows D2 below the flange, cast integral with thedrum. At each side of each opening d is an elongated perforation d2 forthe passage of a bolt. The entire top surface of this flange CZ can bedressed smooth in an ordinary planer.

E designates one of the couplings, used to connect the bottom drum tothe boiler sections. This coupling has a flange E on its bottom havingopen slots E2 on its opposite sides, adapted to coincide with theperforations cl2 beside an opening d', the coupling being securedthereto by bolts E3 passing through said perforatious and slots asshown. The other end of the coupling is also flanged at e, flange estanding perpendicular to flange E', and having open slots or elongatedholes c on each side, adapted to register with perforations in a flangea surrounding an opening a in the side of the section as shown, andbolts e2 passing through said perforations and slots secure the couplingto the section. The coupling E thus constructed forms an adjustableconnection which will not require accurate adjustment of the bottom drumand sections in relation to each other, and can be made by ordinaryworkmen with case and rapidity.

Suitable packing may be used between coupling E and the drum andsections.

The advantages of my improved adjustableconnections over threaded jointsis obvious, and I believe myself the first to use an angle flush jointadjustable as described, in connecting drums to boilers, and obviouslythe invention does not reside solely in the peculiar shape and slottingof the joints, which would necessarily be varied according to thelocations of the drums in relation to the boiler sections. I would alsoconsider it within the scope of my invention if one end of the couplingwas fastened rigidly in any ordinary manner, provided the other endthereof was rendered adjustable and connected in accordance with myinventiom The drums are cast in one piece of alength sufficient toconnect with a certain number lof boiler sections, constituting afurnace;

but as a principal object of sectional boilers is to enable the capacityof the boiler to be increased at any time by simply adding additionalboiler sections, I provide 1for lengthening the drums, by formingsections thereof, as indicated in Figs. 2 and 4. The section Il4 of thetop drum, has flanges B5 at both ends corresponding to the flange B ofthe drum, so that it can be bolted thereto, in place of head B3, whichlatter is then bolted to the outer end of the section, and the sectionhas top and side openings and slotted flanges similar to those of thedrum, as indicated by similar reference letters in the drawings, so thata coupling C can be connected thereto. The section D5 can be similarlysecured to drum D-and has openings, flanges, elbows, and

IIO

perforations, similar to those of drum D, as indicated in the drawings.Thus I can readily increase the capacity of the furnace by addingadditional sections, drums, and connections, without necessarilydisturbing any of said parts, except the front section of the furnaceand its drum connections.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent thereon, is-

l. The combination of a boiler, and a drum: with a flush joint couplingconnecting said parts, said coupling being adjustable independently ofeither the boiler or drum and having flanged ends dressed smooth on theouter faces so as to make close joints with similarly dressed surfacesaround the openings in the drum and boiler and means for securing thecouplings in position, substantially as described.

2. In combination the drum B having longitudinal side flanges b, b andend flanges B', substantially as described; with the drum .section B5,having flanges on both ends similar to flange B', and side flangescorresponding to and forming a continuation of flanges b, b', and meansfor securing the drum section to the drum, substantially as described.

3. The combination of the section having flanged opening, a drum alsohaving a flanged opening, said flanges being slotted or having elongatedholes, with a coupling having both ends flanged to t flush against theflanged -openings in drum and section respectively,

and its anges slotted or with elongated holes to substantially coincidewith the slots or holes of the flanges on section and drum, and boltsplaced in the coincident holes for uniting the coupling to the drum andsection, while allowing independent adjustment of the coupling, so as tomake tight flush joints with both section and drum substantially as andfor the purpose specified.

4. The combination with the drum D having a longitudinal horizontalflange d, and pipe elbows D2 below said flange, substantially asdescribed; of the Vdrum section'rD5 having lateral horizontal flangesimilar toV and forming a continuation of flange d, and an elbow similarto D2, and means for securing the drum section to the end of drum,substantially as specified.

5. The herein described right angled pipe coupling C havingr flanges c Con its ends dressed smooth and slotted or made with elongated holes cC2, the slots on the same side of coupling being parallel so that thecoupling may be adjusted laterally without moving the fastening boltsthereof substantially as and for the purpose set forth.

6. The herein described adjustable pipe connection for boilers anddrums, bent at right angles and having flanges on its ends arranged atright angles to each other dressed smooth on their outer faces andslotted the slots on the same side of coupling being parallel so thatthe coupling may be adjusted laterally without moving the fasteningbolts thereof substantially as and for the purpose set forth.

7. rlhe combination of the boiler, the drum, the angular flush jointadjustable connections between boiler and drum, supporting the drum atone side and the angular leveling rod adjustably connecting the drum toand supporting it on the boiler, at the sides opposite the joints,substantially as set forth.

8. The herein described pipe coupling O bent at right angles having onelong and one short arm; each arm being flanged around its mouth as at c,C', respectively; the flange o having one pair of diametrically oppositeslots c'; and flange C having two pair of outwardly opening oppositeslots C2, one pair of said slots being entirely above the exterior lsurface of the pipe, substantially as described.

9. The herein described elbow pipe coupling E, having flared flanges onits ends, said flanges being perpendicular to each other, and eachhaving a single pair of outwardly opening diametrically opposite slots,the slots on the same side of joi-nt being parallel with each other,substantially as described.
